To all whom t may concern: j y

Be it known that I, Mnn'rm Duinnnicn Boonen, residing at lurley7 Surrey, lling;- land,` have invented certain new and useful Irnprovernenle in Tires .for Vehicles; and .l do hereby declare the following to be a full, clear, and exact description of the invention, such asvill enable others skilledv in the art to which it appertane to .make and une the same. y

' This invention relates to improvements in tires for vehicles, and has more particular' reference to that class which is known as energized, and in yvhieh a solid core 'formed by a plurality C india-rubber Wlndings under tension rey` lees the usual inner tube of a pneumatic tim.

lt is a matter ol Sonie dilllculty to arrange these cores Within the cover, not only be cauSethc cover and core require to be se cured within a rim, but because it iS ahsof lately issential that'no creep or :slip take place relatively between theee col'uponent parte ol the tire. So z ,reat hue been this (flilliculty that in sonne casser; it has` been neccesary to apply an adhesive between the parter whereby to allinaetienl purporaes the core and cover lose their separate identity and their respective funotionn are inlpz'iired. For inetanee the core being' comprensible with a high factor ot ivf-'iliciue it is doeii able that the renilieney be niaiutainml; a good deal ol` it however in lont when an adhesive is applied inrorlioraline; it with the cover, because the latter relatively speaking is no1'1reSilient and incapable of any great degree of tread lexure, owing to the canvas iucorpornted in the care ol' the cover. .Again if the cover be inode flexible and ex tensible `it is dif'ricult to loree the conlbuml core and cover within a riun and it has; been proposed to employ al1/auxiliary rim 'which can be secured in position, while 'the core and cover-tare held intheir relative positions: by cramps. in any jase .it ne necessary lo have a Sentinella) lill up the space between the core and the .riva cthervvilas the rceilicnc of the 'core isinipaxred, and this Seatingvrnunt be capable" 'of outward rad,iaheXpanSion` if the core is to bc forced within the` cover. Heretoiiore it has been cuntoinary to articulate this seating sov that a series of openings occur at equi-spaced intervals., and although there is little if any tendency of' the core to be pinched through my `movement of the Seating parts, yet n plurality oi independent pieces` such as this construction entails is not highly desirable in tire inamlfaoture.

Now accordingl to the present invention the seating formed all in one piece1 but' is capable oitI circanlfercntial distention, so that the core which Sits upon it can be forced 'within the cover, the latter being extensible to accommodate saine. .lrlcnco if the seating be prevented Al'roln collapse et its maximum extension, neither the core, cover nor seating can move since they are relatively locked, the tension-Wound core beingr under compression between the cover and seating; ii'v now the cover has inextensiblc beads then the tire can be placed in the rim with ease il a, divided rim or detachable flange be employed without the necessity of employing` cramps, t losing an auxiliary run.

The in .fention will now be described more parl'ieuln'ly with reference to the accompanying drawings, in which liirurc l is a section ol' the tire7 fitted with the oxpans'siblc seating, Fig. 2 is ance/tional side view ol the tire ehowing the seating with ends overlappingr before being;r cxpaudcd, lligr. il is a sectional side View of the tive showing the elevating exl'mnded and the ends locked.

ln the drawings, 1 is the solid core of the tire; inrloecd in the coVerZ, and restingr on the expaneible seating.;` This seating); is made from flexible steel, aluminium, vulcunile, or other suitable material, and its section is suitably shaped so as to form a goed support ilor the core l. rlhe seating muy be either I olid or ol hollow section and in Vl'ornnd in a dira-onlinuous length and bent into a rirculav hoopi which is arranged within the tire, with the ends overlapping as chown at@ Flex 2.

in operation the core l 1s placed over the seating il, the endsbeing caused to overlap il necrwary, to allow the easy fitting of the core. 'lhe cover 2 is now placed in position over-'thc core and the seatingr and core 'expanded radially by any suitable means until lhe ends of the .seating cease to overlap and abut as shown, at 5 in Fig'. 3. i ln this positiondhe core and cover are held in very close contact and eannbt lnove relatively, the seating' retaining these parts continuously in their co'rcet relationship. ll' the cover he made'ex ensible then there ls some latitude allowable between :the diameter of the seating when its ends abut and the core distention, hut if the cover he 0f 'the Canvas type, then the seatingr diameteil must he c: l.- eulatecl to compress the core Within the cover to fully clistend the lutter, hy the time that its ends abut. It is highly preferable theie- 1to1-e, for this reason if for no other, that the @over he made mainly of rubber.y and of an extensible character. The seating may of course he anchored to the rim with a security stud or like device in any well known manner.

l. In a tire for vehicles halting a coverl and sin inner core the eninhinntinn therewith of 2in expanfsihle senting;v adapted t0 receive i' 'the wie, und when expanded with the ende t abutting, to retain the core und Cover in .tixed l'elutionsh i p.

2. ln atiie tmvehicles, ineen.y for keeping; the cleveland Core in position relative to euch other, consisting` nl n seating having the ends overlapping i'oi nssen'ihly, Suid seating being capable nt expansion nnltil the sind ends meet and ahnt, thereby locking the seating in pnsitim'i relative te the tite parte, snhe-tantinllg' as described and illustrated.

In testimony whereof l alix my signa ture, in presenee nt two witnesses.
